8. RECOMMENDATIONS FOR THE
SELECTIONS OF CABLES
At a short distance of Wiegand readers from the controller (up to 50m),
it is recommended to perform cable with a cross-section of 0.22-0.5 mm².
It is permissible to use any type of signal cables.
At greater distance (50-100 m), a larger cable section (0.75-1.0 mm²) is required,
at least on the power lines of the readers.
Connections of OSDP readers are made using UTP 5 category cable, or special
cables.
When connecting, it is necessary to strictly observe the topology of the «bus» loop.
Also, when connecting, read the recommendations from the manufacturer of the
controller, to which connections will be made.
